Subject [jira] Created: (HADOOP-6755) Have a configurable metric reporting CPU/disk usage per user

Have a configurable metric reporting CPU/disk usage per user
------------------------------------------------------------

                 Key: HADOOP-6755
                 URL: https://issues.apache.org/jira/browse/HADOOP-6755
             Project: Hadoop Common
          Issue Type: New Feature
          Components: metrics
            Reporter: Alex Kozlov


Many organizations are looking at resource usage per department/group/user for diagnostic
and resource allocation purposes.  It should be straightforward to implement a metric showing
the simple resource usage like CPU time and disk I/O per user and aggregate them using Ganglia.

Eventually, we can create an API for pluggable metrics (there is one for Jobtracker and Tasktracker).

Let me know your thoughts.
